Friction-based processes are generally divided into two process families: friction welding (FW) and friction stir welding  (FSW). The common characteristic of each family is that the weld bond is a result of a solid-state welding process.  This offers a number of advantages, including extremely low distortion, ability to weld materials which are considered un-weldable with fusion joining processes, and the ability to weld dissimilar material combinations.

EWI is extremely active in friction-based technologies, and our engineers have driven multiple innovations in the field. We were the first to perfect FSW for hard metals, and have been awarded more than a half-dozen patents in various friction-based processes.
